Thousands of community nurses are striking again over their employers' inability to deliver pay parity after a year of failed negotiations.

Primary Health Care and Plunket nurses have the same responsibilities and qualifications as their Te Whatu Ora counterparts but are paid significantly less.

New Zealand College of Primary Health Care Nurses Chair Tracey Morgan says in some cases they are paid up to 20 percent less than hospital nurses, while Maori and iwi provider nurses are worse off with 25 percent less.

She spoke to Charlotte Cook from the picket line in Rotorua.
